Lette/rs Patent No. 89,144, dated April 20, 1869.

IMPROVEMENT IN GANG-PLOW.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it 'may concern Be it known that I, THOMAS J. HALL, of Bryan, in the county of Brazos, and State of Texas, have invented a new and useful 'I mprovement in Gang-Flows; and I parts.

This invention relates to a gang-plow which is so arranged that the beams can be swung sideways. and up and down at will, and that they can be permanently secured in any desired position. I

The invention consists, first, in a newv device for oscillating the plow-beams, so that their landsides are always vertical, however uneven the ground may be.

The invention consists, also, in a new apparatus for regulating the depth of the plows in the ground, where-y by the depth of furrow is adjusted.

A, in the drawing, represents the proved gang-plow.

Itis made of wood, and consists of two side-bars, a a., of a front cross-bar, b, and of a xed, or revolving, or other suitable axle, c, for the wheels B B, and of other suitable braces, if desired.

From the front bar b is by means of vertical screws C C, suspended'an up-and-down adjustable cross-bar, D, which is slotted to receive the front ends of the plow-beams E. l

The three, or more or less plow-beams are, with their rear ends, suspended by means of cords or chains d (l, from a transverse shaft, F, which has its bearings in the rear part of the frame A, as shown.

lheir fro'nt ends are fitted through the adjustable bar D, and have downward-projecting pins e c, that iit into a perforated plate, f, fastened to the lower part of the bar D.

lhe pins c can swing laterally in the plate f, and thereby'allow the plow-beams to oscillate. They also frame of my imallowthem to be adjusted any desired distance apart, hy being put into the requisite holes of the plate f.

To the cross-bar D are, by means of pins g g, pvoted levers G G, that have forked'front ends fitting around pins h h, that project from the front ends of the plow-bea1ns. l

By swinging the levers G, the plow-beams will be oscillated on the pins c, as aforesaid, so as to bring the plows into the desired position to have their landsides vertical.

The pins g g are also adjustable on the bar D, there being holes Ii i. provided to receive them.

The rear ends of the levers G can, when the plows have been brought into the right position, be locked by means of pins jj, fitted into a cross-bar, k, of the frame A, as shown, a number of holes, l, being provided in k to allow of the lateral adjustment of the plows.

The rear ends of the plow-beams can be elevated or lowered, by revolving the shaft F, in which case the strings d d will be wound on or unwound from the said shaft. v

The shaft can be revolved either directly, by having a crank on it, or by connecting it, by means of a belt or cord, m, with a drinn, n, arranged within convenient reach of the driver for turning.

The plows H H are arranged in suitable manner on the plow-beams, and are of suitable construction.

In front of each plow may be a revolving cutter, I, which is swivelled to the plow-beam or fastened in suitable manner to the saine.

I Aclaim as new, and desire to secuie by Letters Patent- 1. The combination of the up-and-down adjustable the plow-beams E, pins e, and pivoted levers G, all arranged and operating substantially as and for the purpose herein shown and described.

2. rlhe levers G, pivoted to the up-and-down adjustthe plow-beams, and adjusted with their rear ends on a cross-bar, k, all arranged and operating substantially as described, for the purpose of oscillating the plowbeams, as specied.
